With the advantages of cutting metals at high speed and high precision, the fiber laser cutting machines has become the first choice for metal processing equipment in many industries.
To complete the process of laser metal cutting, different components of the fiber laser cutting machine have different functions. Then what’s the function of each part of a fiber laser cutting machine? First, let’s see what components does a fiber laser cutting machne include?
Components of fiber laser cutting machine
The components of fiber laser cutting machine are: main body, fiber laser, control system, cutting head, servo motor, laser lens, etc. Water chiller and Gas tank are the auxiliary equipment.
What are the functions of the core parts?
The functions of the parts of the fiber laser cutting machine are as follows:
The host of the laser cutting machine, which realizes the movement of the X, Y and Z axis, including the cutting work platform. Working bed is using to load materials and to move accurately and correctly according to the control program.
The Fiber Laser is usually called the heart of a laser cutting machine. It’s a device for generating a laser beam needed for cutting. The quality of the fiber laser directly affects the cutting performance and cutting quality of the metal cutter.
As another important part of a fiber laser cutting machine, control system controls the movement of X, Y and Z axis and output of laser power. It’s called the brain of the fiber laser cutting machine.
The cutting head is the output device of the fiber laser cutting machine, which consists of a nozzle, a focus lens and a focus tracking system. Under the control of the control system and the movement of the machine tool, the nozzle moves along the cutting track to realize the cutting of metal materials.
Laser lens occupies a very important position in the laser system, it will affect the power of the fiber laser cutting machine. The laser lens can be selected according to the different requirements of cutting quality.
For different materials and different thicknesses of metal, the height of the cutting head is different, so it is necessary to set the parameters through the control system to ensure effective cutting.
The servo motor plays a role in controlling the operation of the original mechanical parts in the servo system. The high-quality servo motor can effectively ensure the cutting accuracy, positioning speed and repeat positioning accuracy of the laser cutter.
The water chiller is used for cooling laser source and focus lens, reflective mirror in cutting head.
The gas tank is mainly used to assist cutting and blowing of the wastes. Main cutting gases used are: Nitrogen, Oxygen, Air.
How to choose the core components of a fiber laser cutting machine?
A complete fiber laser cutting machine consists of different components. The price difference normally lies in core parts. So how to choose the right core parts and buy the most suitable fiber laser cutting machine with the least money has become a very important matter.
Fiber laser is the most important part of metal laser cutting machine and the core “power source” of a fiber laser metal cutting machine. The fiber laser with the highest configuration currently on the market is: German IPG laser.
Compared with other lasers, this fiber laser has the advantages of higher cutting efficiency, more reliable quality assurance, longer service life, lower maintenance cost, etc.
Raycus laser enjoy the best price versus performance ratio, if you have low budget, it would also be a good choice. Though a china brand, it enjoys good reputaion worldwide.
The control system is the dominant operating system of the fiber laser cutting machine, and its quality determines the stability of the operation performance of the fiber laser cutting machine. It mainly controls the machine tool, realizes the movement of X, Y, Z axis, and also controls the output power of the laser. Generally speaking, most manufacturers will choose Cypcut system for control.
The cutting head of the laser cutting machine is a laser output device, which consists of a nozzle, a focus lens and a focus tracking system. The cutting head of the laser cutting machine will walk according to the set cutting track, but the height of the laser cutting head needs to be adjusted and controlled under different materials, different thicknesses, and different cutting methods.
Servo motor refers to the engine that controls the operation of mechanical components in the servo system, and is an auxiliary motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object. The high-quality servo motor can effectively ensure the cutting accuracy, positioning speed and repeat positioning accuracy of the laser cutting machine.
It is related to the power level of the metal laser cutting machine. It is divided into imported lenses and domestic lenses. Domestic lenses can be divided into two types: imported materials and domestic materials. The price gap is very large, the use effect and the service life also have big differences.
The above is the main content of how to choose the core parts of the fiber laser cutting machine. It can be seen that a complete fiber laser cutting machine is composed of many parts. We should learn more knowlege before made the final decision on the fiber laser cutting machine.
